Great photo, Jeremy. I like how the wide aspect ratio matches the long, narrow "slit" through which the water pours. In fact, by reducing some of the unecessary foreground and cropping the bottom of the slightly warm circle of light in the top middle, the concept could be strengthened.
Yes, you could go back and shoot it with a longer exposure for a different effect, I think the image is a strong one already due to the textures you've captured. It's a very tactile photograph. Nicely done.
BTW, if you are tempted to go back in winter, let me know and I'll tag along!
